AS-Interface devices for valves and valve actuators

position feedback

An inductive dual sensor provides innovative feedback for quarter-turn actuators. It detects the open/closed position by means of a puck mounted on the axis of rotation. The integrated AS-i connection at the same time provides the voltage supply and bus interface.
Using the valvis linear sensor, continuous strokes (e.g. in sanitary valves) can be detected.

position feedback and valve control

The ifm dual sensors of the T family are suited for the control and position feedback of pneumatic quarter-turn actuators.
Up to 2 input and 2 output signals are transmitted at a low cost via a 2-wire bus cable (AS-interface). Up to 62 actuators with solenoid valve can be triggered via one AS-i master. For diagnostic purposes, wire break and short-circuit are monitored on the valve.
